esponse to specific user input are not required. You should also think carefully how your design will respond when viewed on a mobile device screen (i.e. 375px wide. portrait orientation) and include two 'interactive' wireframes (two pages) to illustrate how the solution might appear on a mobile device screen. Your wireframes must be submitted as a set of one or more HTML files and may also include CSS and image files. You can use Pencil, a text editor, or any other tool with which you are familiar to create these files. Submitting your wireframes in any other format will result in a penalty being applied. Should you decide to use Pencil, you must use the 'Export Document' option to export your wireframe as a 'Single web page' using the 'Default HTML Template. This creates a HTML file and a folder of images which ensures that the client can review your wireframe without the need to install the Pencil application. You should not make any further changes lo these files and make sure to include them all in your submission
